Effective On-Site Supervision- A Yardstick to Minimizing Building Construction Failure In Southwest Nigeria

The building construction industry plays an essential role in the development of any developing nation. Despite various regulations and professional guidelines in the building construction sector, Nigeria continues to experience frequent building failure. This research therefore aims at assessing the effectiveness of on-site supervision as a yardstick to minimizing building construction failure in Nigeria. Data were collected from 108 stakeholders in the building industry via a well-structured questionnaire. Result findings show that in Nigeria building construction site, the supervision practice is often done daily, and site engineers are clearly at the forefront. The on-site supervision was found to be effective in Nigeria Building industry, indicating a strong overall confidence in the supervisory process. Although corruption and bribery were identified as major challenges, and they have considerable negative impact on the perceived effectiveness of supervision. Results also show that there is a potential gap in the consistent application of building regulations. It is therefore recommended stricter enforcement of building regulations be made, and the adoption of modern technology such as drones, AI monitoring, as these will ensure proper supervision techniques, and reduce the likelihood of construction errors, thereby minimizing failures of buildings in Nigeria.
